Well that's the end of btrfs for me; barely a month in it's shat itself and taken my /home with it.
I've lived this long without metadata checksum and snapshot...
I was able to extract a list of trees, even though it wouldn't mount, even with the various recovery options, using
btrfs-find-root /dev/mapper/vgkubuntu-home
This will split out a bunch 'well' things. I got lucky and when I passed the number of one of those to
/tmp as tmpfs - https://wiki.archlinux.org/title/tmpfs
logs that don't go on forever - https://github.com/azlux/log2ram
systemd logs that don't go on forever /etc/systemd/journald.conf:
SystemMaxUse=50M
Faster, more responsive kernel (if stuck on an LTS for everything else) : https://liquorix.net/#install
Edit This no longer works on the latest firmware because the calls are now encrypted. It's trivial to reverse with the AES key just being based on timestamp, but there is an easier way :
Monitoring Powerline speeds ( TP-Link TL-WPA8630P, TL-PA8033PKIT, AV1300)
Firstly, you'll need to use your web browser's network debug panel to intercept a login request to the access points web GUI.
You'll want to find the 'Basic admin' cookie.
This keeps all your data and most settings intact, so you can use your phone as you do it (though it will spend a lot of time 'optimizing apps') or stop and go out :-)
You don't need to unlock the boot loader, so the camera quality stays awesome, and you get all the bundled apps, along with the Google ones.
Use the built in update app to go from 4.4 to 5.
Then use the settings, about, update menu to update to 5.1 latest.
Install Kingroot (I used 4.8) and let it root your phone.
To to find your IP :
alt-f2, lxterminal
ifconfig
SSH in from another machine, and follow along from https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1492441/comments/7
Quick note on these PowerLine devices.
They don't need any tools to manage them, as they have a sufficient web interface.
BUT - these devices are terrible network citizens.
I got a Dell laptop a few years ago, and while scouting around for it's replacement I noticed the Ubuntu Linux folks are still proud to say their stuff not only runs on Dell kit still, but that it's available to purchase and have supported direct from Dell:
"purchase Ubuntu on Dell"

For reason's best known to some brain dead marketing monkey, I got given a USB device that only works correctly on Windows. Have you ever seen a ghost in the machine open the run box, type in a web address and launch a browser with out asking ? Neither had I, and fortunately Linux and MacOS users don't have that problem. But how to get your free credit from the AWS Summit 2011 ?
I found a way.
Keynote
Mike Jones, Adobe
Mike is an evangelists for games at Adobe. A shift of focus I think Adobe is still making. Mike shows there are a massive number of devices, and you can target these all with HTML5 but Flash has a unique opportunity to innovate on all of these platforms. Mike has a nice time line graph to back this up over the last 15 years.
Keynote
Mark Drew and Gert Franz of Railo
It's up to you to be proud of CFML, don't apologise for it ! Tweet it, blog it ! You cant convert .Net, PHP users, only tempt them.
But likewise, we should try other stuff and tell everyone the 10% you like about Scala or whatever. You might end up with them in ColdFusion (or Railo !). Incentivise your colleagues, especially the 9 to 5'ers.
Price and performance is not an issue any more for ColdFusion, been around for ages but updated every single year.
